Abstract
A method of making a wind turbine blade comprises stacking a plurality of strips of fibre-reinforced polymeric material one on top of another to form a stack of strips (40); strapping the stack of strips together by means of at least one strap (41) made from a fibrous material, and thereby forming a strapped stack; infusing the strapped stack with resin; and curing the resin to form an elongate spar structure in which the at least one strap (41) is integrated with the stack of strips.
